Be it known that Ll llio'snn, a Clisin zen o the limited S'aes, i esiding at illhevios. in the county of Hamilton and Siate 5 Ohio, have inven'iefl certain new emi useful 'inproveniens in Conrolling Mechanism for ./'Lutornohile-l-leaers7 of which he fol-- lowing is a speeiiication.

My invention relaes so improvements in controlling mechanism for automobile heaters.

@ne of'ls ohieets is to prsvifle improved. 'valve meehanisin` adapted 'to be introfluceel in the motor exhaust pipe 5o control the. z'iow o of rnoorehaust so as to direct all or pari;

of said exhaust 'through a hei r.

Another object is so provide .improved means izo reliably and eonfvenien'bly operaie said valve.

My invention further consists in Certain details of forni, combination and. a rangea ment, all 'of which will he fully forth in the description of he accompanying drawings, in. Whish; v

A represens the frame of :in auornohile represents he housing ,in which the motor eonlaone..l anni. represens the molor ern sust pipe through which the motor en aiisa Whiel'i may he steam, hut is usually ie heaiefl from 'a heat or' explosion I ine, is conducted usually through inizi.'1 2 and escapes into the air at the rear of che automobile. heater l) is le'y inlo he floor E. of the anions( ile in position o 'warm fthe occupants thereol` in eolcl ii'eatherj and is connected byineans of a hi'aneh pipe l wicl'i she xnosor exhaust pipe C so that all or a portion of the exhaust gases may he pipe C into saiil .healer lo se 'warniing eii'eeK l. l -he pipe C shan branch ai, 'to reiirn the exhaustto the pipe C after passing'hrough ehe heater.

ln order to direct the exhaust gases from pipe U into the heater l preferably employ a valve having a "ishaped casing 6 inthe exit bra' ches 7 and 8 of which pvotally supported valves 9 and l0, the stems 1l and l2 of which proj-ect outside the casing and are eonnee'feel so as to 'move in unison. For this purpose l. preferably employ' wo segmental gears 13. lfhone of which is provided with s'sop lugs l5 at opposite ends to liinifI she movemeni; of she gears and valves.

soothed member 5 6 on ehe stem 1l is engaged oy a spring 17 to hold the Valves 9 and l0 to any adjusted position. The spring l? is held. in posiigion in e slot in a boss 18 formeel integral with the Valve casing by means ol a sel; screw l2),

As illustraecl in Fig. Li the Valve casing is provided with oil-seis or shoulders 20 adapt eel to he dressed by machinery, against which shonlelers she faces of 'the valves 9 and4 l0 seat and make close joints when said Valves are closed.

ln the niodileaion Fig. 5 the shoulders Q0 are omitted and the valyes when closed Closely fit he hores of lhs branches 7 and 8. In order io secure the valves to their stems the stems li. amil l2 inside the valve casing ai slol ed and the Valves, preferably in the mail of clim-s of shei-at metal are inserted in said slots and lselverl in place by means of 13s-iter sins 2l. l preferably provide the branch 5 of she easing 'with a nulle ihre-sel to h a union Q2 is adapted to be attached 1o eonveniently make connection with the heater within @he limited space available, and to permit of readily' detaching the heaer during Warm Weather.

l n order o reliably and conveniently operste the valves controlling the admission of hoi; gases so the heater l provide a sprocket or Chain Wheel 3G ataehed to the stem o' one of ifalves, say the stem 11. il. sprocket wheel 3i is pivoally attached to izhe frame preferably on the :inside of said freine piece se hat the ends o1 'the teeth' the wheel 80 and valves oliierativ'ely connected thereto by means of a sprocket chain 32.

The *spring 1'? locks thc valves against ac-` cidental displacement in any position to which they may be adjusted. f The valves 9 and l0 are set so that when one is fully open the other is fully closed, and so that any desired proportion of opening in the respective branches may be attained. Tlie valve adjusting and transn'xission mechanism is extensible in. nature and such as 'to be readiiy applied to various styles of automobiles, and is adapted te 13e/readily and positively operated at all positions of the valves as the transmission .mechanism has no dead centers or positions at which they are operated with more ditiiculty `than at others, which would be liable to interfere with their adjustment to secure the desired amount of heat in the heater.

The mechanism herein illustrated and described is capable ofgoonsiderable modificationwithout departing from the principle of my invention.

Having described my invention, what I claim is: t

l. .In a controlling valve mechanism, a valve adapted to be introduced into the exhaust with a branch sprocket wheel and adapted to said valve to out pipe to lead to a heater, a operatively connected with control the movements of oit` or supply heated gases to said branch pipe, a sprockct'wheel pivotally mounted with its teeth in position to be engaged by the foot of the operator, and a. chain to'transmit motion from one of said sprocket wheels to the other.

2. In a controlling valvev mechanism, a heater, an exhaust pipe pipe ot an automobile' and provided having a branch leading to said heater, a valve introduced into the vexhaust to control the supply of heated ases to said heater, a sprocket; wheel ivota ly mounted relative to the frame of said automobile with its teeth in position to be engaged by the foot of an operator, a chain to `transmit motion from one of said sprocket wheels to the other, and mechanism to yieldingly lock said'valve to 4different adjusted positions- 'a caslng having an "inletand two exit pivotally supported in each of said exit branches, and transmitting mechanism operatively connecting said valves to cause them to move in unison and so as to close one of said exit branches when the other is open, a sprocket wheel operatively connected with and adapted to actuate said valves to' heated gases to said heater,- a sprocket wheel pivotally mounted relative to the frame of said automobile with its'l teeth in position to be engaged by the foot of an operator, and a chain t0 transmit motion from one of said sprocket Wheels to the other.

In testimony whereof I have affixed my signature in presence of two Witnesses.
